A Surprisal-Based Greedy Heuristic for the Set Covering Problem
Algorithms, 2023 In this paper we exploit concepts from Information Theory to improve the classical Chvatal greedy algorithm for the set covering problem. In particular, we develop a new greedy procedure, called Surprisal-Based Greedy Heuristic (SBH), incorporating the ...
